tion of the experimental data available on this question 

 in 1904, Rommel l concluded that approximately 12.26 

 per cent of the small grains is saved by grinding. 



Cooking. 



As the result of numerous practical feeding tests, it has 

 been definitely established that the old-time practice 

 of cooking feed for pigs is a detriment rather than a bene- 

 fit. A compilation of the results of seventeen experiments 

 by Henry and Morrison 2 in which corn, barley, peas, 

 and various combinations of these were fed cooked and 

 uncooked, showed in every instance but one an actual 

 loss from cooking. The averaged results showed 100 

 pounds of uncooked grain equal to 114 pounds of cooked 

 grain. 



Cooking feed for swine may be justified and even bene- 

 ficial under certain special conditions, however. In 

 fitting hogs for show, a few breeders believe that the 

 highest condition of bloom is facilitated by cooking the 

 feed, although, no doubt, the tendency is to exaggerate 

 the benefits. Sick animals or those out of condition may 

 be helped, also, by an occasional ration of cooked feeds. 



Proportion of water in slop. 



Although ground grains give a little better results when 

 fed wet than dry, the proportion of water in the slop does 

 not appear to be important except when excessive quanti- 

 ties are supplied. This is indicated by the results of a 

 trial made by Plumb and Van Norman 3 at the Indiana 

 Station as shown in Table CLXVI.
